Comparison of lacZ expression from the PtetA and PBAD promoters in V. cholerae. (A) An overnight culture of V. cholerae JB58 (pXB300-lacZ) was diluted 1:100 into LB broth supplemented with Cb and the indicated concentrations of aTc. The cultures were then incubated at 37°C with shaking for 2.5 h before quantification of β-galactosidase. (B) An overnight culture of V. cholerae JB58 (pBAD18-lacZ) was diluted 1:100 into LB broth supplemented with Cb and the indicated concentrations of L-arabinose. The cultures were then incubated at 37°C with shaking for 2.5 h before quantification of β-galactosidase. The results are the average ± SD of three experiments.
